First Impressions of ONYX A/M-33 Impulse
The ONYX A/M-33 Impulse is marketed as a top-tier personal flotation device (PFD), designed to keep boaters safe without sacrificing comfort or mobility. Coming from a background where I’ve seen firsthand the critical role a PFD can play in survival situations, I was eager to evaluate whether this model lives up to its promise. The ONYX A/M-33 Impulse boasts automatic/manual inflation and durable construction, features that immediately caught my attention.
Years ago, while navigating a white-water stretch of the Snake River, a sudden rogue wave capsized my kayak. My standard PFD, while functional, felt bulky and restricted my movement as I fought to right myself and recover my gear. The experience underscored the necessity for a PFD that combines buoyancy with freedom of movement, something I hope the ONYX A/M-33 Impulse delivers.
Upon unboxing, the ONYX A/M-33 Impulse impressed me with its sleek, low-profile design. The materials felt robust, yet surprisingly lightweight at only 2.1 oz (as listed in the specs). The build quality appeared top-notch, with clean stitching and a secure-feeling inflation mechanism.
Compared to my older, bulkier PFD, and even more streamlined options from brands like Mustang Survival or NRS, the ONYX A/M-33 Impulse seemed to offer a significant advantage in terms of wearability. I chose this model specifically for its auto-inflation feature, something my previous PFD lacked, and the promise of unrestricted movement. My initial reaction was definitely positive, a feeling of excitement to put it to the test and see if it truly offers the best of both worlds: safety and comfort.
Real-World Testing: Putting ONYX A/M-33 Impulse to the Test
First Use Experience
My initial testing ground for the ONYX A/M-33 Impulse was a calm water fishing trip on Lake Tahoe. I wanted to gauge its comfort during extended wear and assess its performance in a relatively benign environment before venturing into more challenging conditions. The weather was sunny with a slight breeze, presenting ideal conditions for a comfortable day on the water.
The ONYX A/M-33 Impulse proved incredibly comfortable to wear while casting and reeling. It didn’t impede my movements like traditional PFDs often do. I barely noticed I was wearing it for the first couple of hours.
After several hours of use, I intentionally submerged myself briefly to test the auto-inflation. The inflation was rapid and provided substantial buoyancy. There were no issues, but it was shocking in the moment and I’m glad I was prepared.
Extended Use & Reliability
After using the ONYX A/M-33 Impulse for several weeks on various boating and fishing trips, I can confidently say it holds up remarkably well. The materials show no signs of significant wear, despite exposure to sun, saltwater, and occasional splashes of fish slime. Cleaning the PFD is a breeze; a simple rinse with fresh water and air drying is usually sufficient.
Compared to my old foam PFD, the ONYX A/M-33 Impulse is a game-changer. It’s far more comfortable, less bulky, and offers a higher level of safety due to the auto-inflation feature. It has exceeded my expectations in terms of comfort and convenience, although the long-term durability of the inflation mechanism remains to be seen.

Performance & Functionality
The ONYX A/M-33 Impulse excels at its primary job: keeping you afloat. The auto-inflation is a lifesaver, providing rapid buoyancy when needed most. It is also reassuring to have the manual inflation option as a backup.
The comfortable design allows for unrestricted movement. This makes it ideal for activities like fishing, paddling, or sailing, where freedom of motion is essential. The only area that could potentially be improved is the neck opening, which could be slightly wider for enhanced comfort, although this might compromise the overall fit.
Design & Ergonomics
The build quality of the ONYX A/M-33 Impulse is impressive. The materials feel durable and well-stitched. The low-profile design is a major plus, making it far less cumbersome than traditional PFDs.
The PFD is generally user-friendly. The auto-inflation mechanism is straightforward, and the manual inflation pull cord is easily accessible. The only slight learning curve involves understanding the proper way to repack the PFD after inflation, which requires careful folding and CO2 cartridge replacement.
Durability & Maintenance
With proper care, the ONYX A/M-33 Impulse should last for several seasons. Regular rinsing with fresh water after exposure to saltwater is crucial to prevent corrosion. Replacing the CO2 cartridge after each inflation is essential for maintaining its functionality.
Maintenance is relatively simple. The outer shell can be wiped down with a damp cloth, and the inflation mechanism should be inspected periodically for any signs of damage. The key is to avoid harsh chemicals or abrasive cleaners, which could compromise the materials.
Accessories and Customization Options
The ONYX A/M-33 Impulse doesn’t come with a lot of accessories, focusing on simplicity and functionality. The primary accessory is the CO2 cartridge, which is essential for inflation and must be replaced after each use.
Customization options are limited. Aftermarket accessories could include whistles or small knives that can be attached to the PFD, but these would need to be carefully chosen to avoid interfering with the inflation mechanism. It may be compatible with accessories with universal attachment designs.

Who Should Buy ONYX A/M-33 Impulse?
The ONYX A/M-33 Impulse is perfect for boaters, anglers, kayakers, and anyone who spends time on the water and values both safety and comfort. It’s particularly well-suited for those who engage in activities that require freedom of movement, such as fly fishing or sailing. It’s great for anyone where auto-inflation is desirable.
Someone on a tight budget or who only occasionally boats in very controlled environments might find a more basic, less expensive PFD sufficient. Also, individuals who are uncomfortable with the potential for accidental auto-inflation may prefer a manually inflated PFD.
A must-have accessory is a spare CO2 cartridge. Having a backup on hand ensures you can re-arm the PFD quickly after inflation. A small waterproof pouch for carrying essential items like a whistle or signal mirror would also be a worthwhile addition.
